Toro Rosso explain double mechanical DNF in Russia

Toro Rosso team principal Franz Tost has explained why both of the team's cars retired from the Russian Grand Prix after just four laps, as the brakes caused both cars to randomly spin out on Sunday.

Both of the team's cars already started from the back of the grid after taking penalties for changing engines, and the early retirements just added insult to injury. Strangely, both Brendon Hartley and Pierre Gasly spun out in the same way on almost the same part of the track, raising some eyebrows around the paddock.

They both returned to the garage, with Gasly reporting that he had no brakes and Hartley having similar symptoms.

"It was a frustrating Sunday for Toro Rosso as both cars had to retire," Tost recalled to Motorsport.

"For whatever reason we ended up with very hot front brakes and one piston in the calipers got stuck.

"This caused the overheating of the brake fluid and a long pedal.

"Therefore, we called the drivers to come to the garage.

"Obviously, being in parc ferme conditions, we didn't change anything from yesterday, so we need to investigate further what the reason is."

With Honda's home race coming up this weekend in Japan, Toro Rosso will hope to give the fans at Suzuka a longer taste than they did in Russia!
